THERMOMETER-CASE.

Specification of Letters Patent.

Patented Feb. 19in, 1918.

Application filed February 2, 1917. Serial No. 146,180.

To all whom t may concern:

be 1t linown that 1, .HARRY S. WRIGHT, a citizen or the United btates, residing at Jerome, in the county of Lincoln, rotate of idaho, have invented a new and Vuseful 'l hernionieter-Uase; and .i do hereby'declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to maire and use the same.

'lhis invention relates to an improved casing or case Jr'or thermometers used by physicians and the lilie in tahing the temperature of patients. i

Une or' the objects of the invention is to improve, siinpliry and render Ymore practical the thermometer casing or case illustrated, described and claimed in the application of li. t5. Wright, filed April 1316, Serial Number 89,2al, allowed August 17, 1916.

Another object of the invention is to provide an outer casing to be constructed of any suitable material, preferably glass, or the like, provided with an inner tube of some suitable absorbent material, there being a space between the inner tube and the outer tube for the reception of some suitable antiseptic solution for saturating the inner tube, whereby the fumes will act as an antiseptic for the thermometer, which enters the inner casing, so that contagion following the repeated use of the thermometer is obviated.

A further object of the invention is to provide means consisting of a rubber washer at the top of the inner casing, through .an opening of which the thermometer is inserted, in order to wipe the thermometer as it is inserted and removed.

A further object of the invention is that the washer engages an annular groove of the outer casing to hold the inner casing in lace.

p A further object of the invention is the provision of a guide adjustable in the outer casing so as to guide the thermometer into the opening of the rubber washer.

' In practical fields, the details of construction may necessitate alterations falling within the scope of what isl claimed.

The invention comprises further features i and combination of parts, as hereinafter set forth, shown 1n the drawings and claimed.

In the drawings Figure 1 is a View in side elevation ofthe improved thermometer casing.

Fig. 2 is a vertical sectional view through the same showing it constructed in accordancewith the invention. l

Fig. 3 'is a sectional View on line 3 3 of Fig. 2.

Fig. 4 is a transverse section on line 4--4 of Fig. 2. Y

Referring more especially to thedrawings, 1 designates a casing which may be constructed of any suitable material, preferably glass or the like, in the form of a tube closed integrally at one end, as shown at 2, the other end is open and is provided with an exterior threaded reduced part 3, to be engaged by the interior threads t of the cap or closure 5. The inner wall of the casing 1 is providedV with an annular groove 6, for the reception of the'rubber washer 7, which has a central opening 8, smaller in diameter than the cross sectional diameter of the thermometer'Q. Arranged in the casing 1 is an inner tubular casing 10, which may be constructed of any suitable absorbent material, for instance, material similar to blotting paper or the like, and which has suflicient stiffness or rigidity, whereby said tube 10 may hold its shape. The inner tube 10 is so arranged in the casing l as to provide a space 11 for the reception of any suitable antiseptic solution. The inner tube 10 has its end 12 closed and its end 13 open. The lower extremity 12 of the inner tube has a projection 14, to prevent the end portion 12 from contacting with the inner lower end of the casing 1. The exterior of the inner casing or tube 10 at both ends is provided with annular flanges 15 and 16 which hold the casing 10 spaced from the casing 1. The lower flange 15 is provided with notches 17. The antiseptic solution is first placed inV f the casing 1, then the inner casing 10 is inserted, .the solution passing through said notches'lY, so as to fill the space 11 between the inner tube and the casing 1. The Harige 16 closes the upper end portion of the space 11, and when the inner tube 10 is so ary lo Y Yac ljaeent the'lage 16, to holdtheinrier tube 10 seeurely inv place' and' against movement,
